IMPROVEMENT IN MACHINES FOR PASTING AND FOLDING COLLAR-ENDS.

Specification forming part of Letters Patent No. 171,586, dated December28,1875 application filed Y November 4, 1875.

To all whomit may concern:

Be it known that I, CHARLES SPOFFORD, of Boston, in the county ofSuffolk, State of Massachusetts, have invented a new and usefulImprovement in Machines for Folding and Pasting the Ends of Collars andother articles, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawing. in whichFigure 1 represents a side view. Fig. 2 is a longitudinal verticalsestion. Fig. 3 is a plan or top view.

Similar letters indicate corresponding parts.

This invention consists in the combination, with a folding-table, apastor-roller, and one or more carrying-chains, of a reciprocatingdepresser and a" reciprocating folder, so that a collar or other articleplaced on the table is carried, and its end, after having been suppliedwith paste on its under surface, is folded by the combined action of thedepressor and folder. With the folding-table, the carryingchains, andthe folding mechanism are combined compressing-rollers and aheating-drum, so that the end or ends of the collar or other article,after having been supplied with paste and folded, are firmly compressed,and then dried, and that, after the article leaves the machine, thepasted end or ends are firmly retained in the required position.

In the drawing, the letter A designates the folding-table, which isprovided with two slots,

at a, in which work the carrying-chains B. These chains are providedwith studs 1) 1), projecting up above the surface of the table, and setat regular distances apart, so that when motion is imparted to thechains a collar or other article placed on the table will be carried intoward the folding mechanism. On

the table are secured two guide-strips, c c,

placed at such a distance above the surface of the table that thecollars or other articles to be acted upon can pass between them and thetable. Suitable gages d d are secured on the table near its receivingend, so that the collars or other articles can be readily brought in theproper position. The chains B B are stretched over wheels 0, mounted ona shaft, D, which is situated at the receiving end of the table, andover a drum, E, whichis situated at the from a suitable cistern in anydesirable manner. Said pasting-segments F are situated beneath theapertures ff in the table A, and as they revolve the paste previouslydeposited on their peripheries is transferred to the ends of a collarorother article carried over the table by the chains B, the motion ofthe chains and of the pasting-segments being so timed that theyco-operate in the manner above stated. After the collar or other articlehas passed the pasting-segments its ends are turned down by thedepressers G G, and then folded inward by the folders H H. Thedepressers G G are secured to arms 9 g, which extend from a rock-shaft,I, that receives an oscillating motion by means of a cam, J, mounted onthe shaft D. Instead of securing the depressors to a rock-shaft,however, they may be attached to a slide, which receives a rectilinearreciprocating motion. The folders H are secured to "slides h h, whichreceive a reciprocating motion by cams K K, mounted on the shaft D, themotion of the depressors and folders being so timed that they do notcome in conflict with each other. After the ends of the collar or otherarticlehave been folded, said ends are carried up by the chains B on theinclined planes ii, and as the motion of the chains proceeds the collaris carried through under the pressing-rollers L to the drying-drum E, onwhich the same is retained by tapes n a, which retain its ends in closecontact with said drum until the latter has completed aboutthree-fourths of a revolution,

vwhen the collar is deposited in-a suitable receptacle placed beneaththe table A. In order to efiect this purpose the tapes are carriedaround the pressing-rollers L, and thence one strand of each tape passespartially around the heating-drum, while the other. strand runs overguide-rollers j k lm, until it meets the first strand.

After the collars or other articles have been discharged from mymachine, as above described, they are in the proper condition to bepacked up without further delay.

What I claim as new, and desire to secure by Letters Patent, is

1. In a machine for folding and pasting the ends of collars and otherarticles, the combi- 1 nation, with a folding-table, a paste-roller, andone or more carrying-chains, of a reciprocating depressor and areciprocating folder, constructed and operating substantially as shownand described.
